| 摘要 |
<p>The invention relates to an expansible fixing plug (10), which is manufactured as a two-material fixing plug from a relatively soft and a relatively hard plastics material. To achieve a low insertion torque of an expansion screw as the expansible fixing plug (10) is expanded, yet nevertheless a high anchoring force, the invention proposes constructing from the relatively hard plastics material expansion fingers (22), having cross-sectional areas increasing in size in the direction towards the leading end of the expansible fixing plug (10), which expansion fingers are embedded in expansion tongues (14) of the relatively soft plastics material having a cross-section corresponding to a circular segment, the expansion tongues (14) being connected with one another by dilatation zones (16).
